| description | A battery management system according to the present invention is used for a battery that is connected in parallel to a rectifier filter capacitor via a high-voltage-side power line and a low-voltage-side power line. The battery management system comprises a discharge control switch connected between a first node and a second node of the low-voltage-side power line, a temperature sensing circuit including a thermistor, wherein a first end of the thermistor is connected to the first node; a pre-charge switch connected to a pre-charge power line between the second end and a second node of the thermistor; and a control unit. The control unit is configured to turn off the discharge control switch and turn on the pre-charge switch, for pre-charging of the rectifier filter capacitor, when a key-on signal is received.
